      Optical Engineer Interview

      18 Nov 2025
      Anonymous interview candidate
      San Diego, CA
      No offer
      Positive experience
      Easy interview

      Application

      I applied through an employee referral. I interviewed at ASML (San Diego, CA) in Oct 2025

      Interview

      The process started with a ~30-minute phone interview with an optical engineer. He briefly introduced the company and team, then asked about my background, education, and several projects I’ve worked on. We talked about my experience in optical design, simulation and fabrication, and he asked which locations and teams I was interested in. At the end he explained which optical engineer positions might fit my profile, the timeline for feedback, and the possible next steps in the interview process.

      Interview questions [1]

      Question 1

      Can you walk me through one recent project that best shows your optical design experience and explain your specific contribution?
